With unique machining method, lesser cutting force and no thermal influence on target material, the AWJ has a wide range of machinable materials [1].
The impact pressure of waterjet is prone to cause crack in brittle materials because of the stress waves interference or distortion up to remove in plastic materials [8].
Hence, under the action of stagnancy layer, static pressure cracks will occur in brittle materials and plastic distortion will occur in plastic materials.
Under the action of contact stress, micro-cracks in brittle materials or irreversible deformations in plastic materials will occur on the bound of contact crater where contact stress reaches maximum.
